What was the battle of Dingtao? How did Cao Cao defeat Lu Bu?

in the war of Cao Cao's unification of the north, Cao Cao, then the secretariat of Zhou, captured Dingtao in 195 and expelled the forces of Fenwei general Lu Bu, which was called "the Battle of Dingtao" in history.

after Cao Cao attacked Lu Bu and Puyang, he rallied, so in the first month of, he defeated the army of Lu Bu who invaded Dingtao (now the northwest of Dingtao District, Heze City, Shandong Province).

In May, Cao Cao launched an attack on Jiang Lan and Feng Li by Lu Bu, a garrison in Juye (now northeast of Shandong Juye). Lu Bu personally rescued him, and was defeated by Cao Cao and retreated. Cao Cao annihilated Juye's defenders, beheaded Jiang Lan and Feng Li, and marched to Cheng's (now southwest of Juye, Shandong).

At this time, Cao Cao learned that Tao Qian, a herdsman in Xuzhou, was dead, and planned to seize Xuzhou and return to the army to destroy Lu Bu. Counselor Xun Yu pointed out that Yanzhou (the northwest of Yuncheng, now Shandong Province) is the base for you to think about the world. At present, we should pay close attention to fighter planes, harvest cooked wheat, store grain, accumulate strength, and concentrate on eliminating Lyu3 bu4, a confidant.

Then, they marched into Yuan Shu, a separatist region in Yangzhou, to control the Huai and Si river basins. If we are now on an expedition to Xuzhou, Lyu3 bu4 will certainly take advantage of it, and Yanzhou county may fall into the hands of Lyu3 bu4. Before attacking Xuzhou, there were many killings, and it was inevitable that people would fight for themselves. Without surrender, they could break it, but it was hard to find evidence. If the soldiers and civilians in Xuzhou stand firm and clear the field, and are ready for battle, and cannot be conquered for a while, you will be in a dangerous situation of being stranded and homeless. Cao Cao took Xun Yu's advice and gave up his attempt to attack Xuzhou.

Soon, Lu Bu set out from Dongjin (now Jinxiang, Shandong Province) to meet Chen Gong, and led 1, troops to attack Cao Cao. At that time, Cao Cao was collecting wheat outside, but there were only a thousand people staying in the camp. There were long dikes in the west and Woods in the south. Cao Cao immediately assembled his troops, ambushed behind the long embankment with the main force, and sent a force array to challenge.

Lu Bu thought that Cao Cao and Serenade were leading an army to make an emergency attack. After being lured into the ambush area by Cao Cao, the ambush rose, and the troops of Lu Bu were jointly attacked by foot and riding. Lu Bu's army was defeated and fled, followed by Cao Cao, and arrived at Lu Bu's camp. Lu Bu was unable to fight, and he was afraid of being besieged by Cao Jun, so he abandoned the camp overnight and withdrew to Xuzhou. Cao Cao attacked Dingtao City and sent troops to recover Yanzhou counties.
